2. Overview
2.1 Brief Introduction
MIG series of welding machines adopts the latest Pulse Width Modulation (PWM) technology and
the Insulated Gate Bipolar Transistor (IGBT) power modules. It uses switching frequencies in the
20KHz-50KHz range so as to replace the traditional line-frequency transformer type welding
machines. Thus, machines are characterized with excellent dynamic response, portability, small size,
lightweight, low energy consumption, etc.
MIG
series of welding machines uses Mix gases as shielding gas to realize gas shielded welding,
active gas

as
shielded gas to realize MIG welding.
MIG
series of welding machines has built- in automatic protection functions to protect the machines
from over-voltage, over-current and over-heat. If any one of the above problems happens, the alarm
lamp on the front panel will be lit and output current will be shut off automatically for the machine
to protect itself and prolong the equipment using life.
MIG series features:
1. Digital control system, real-time display the welding parameters;
2. High performance multifunction power source (MIG/MAG);
3. Waveform control, stable welding arc;
4. IGBT technology, low power consumption;
5. Rated Duty Cycle

GRAND MIG 200 MULTI PFC SYN MV = 200A @ 30%(40°C)
GRAND MIG 200 MULTI PFC SYN MV has another feature: synergic control of the welding
current and voltage.
MIG series of welding machine is suitable for all positions welding for various plates made of
stainless steel, carbon steel, alloyed steel, copper, titanium, etc, which is also applied to pipe
installment, mould mend, petrochemical, architecture decoration, car repair, bicycle, handicraft and
common manufacture.
MAG = Metal Active Gas Welding
MIG = Metal Inert Gas Welding
